Fuel filter

It's flowing towards the engine from the fuel tank.
Looks to me like the fuel pressure is too high, any Idea what pressure you are running?
Don't know what it's set at, just left the dyno 400 miles ago..didn't have any issues until recently..missing at 5k 18 psi at wot..barely getting any fuel pressure now..
I'm installing the electric water pump this weekend when I get the cross over pipe gaskets, ill install a new filter in there and see if that helps..
I had the 03/04 converted cobra fuel tank installed btw. From Glenns Performamce
You don't have a gauge in the car or on the regulator or schrader valve?
How are you setting the fuel pressure?
I have a Guage on the a pillar, and an adjustable regulator, but no Guage that tells me what it's set at.
I'm sure the guy that had the car on the dyno has all of that info.

So I replaced my leaking electric water pump, put new plugs in and a new fuel filter in..at idle it was showing 22 psi..still breaking up and going below 20 psi when I nail it...so something is not right with the new fuel system I just had installed..maybe a bad regulator, or pump...idk..I'll call the shop on Monday and see if they have any ideas..needs to go back on the dyno.
That fuel pressure is about half of what it should be. What regulator do you have?
What water pump are you running? I have a Meziere electric pump. I've had it for well over 10 years and haven't had a single problem with it.

Yeah, that's what I was thinking, after the filter change it sits at like 30 psi at idle.i have the same pump. I had left my car in the garage for about 10 years before putting money into it again..I bought a new pump but didn't change it until I noticed a leak.. I coulda changed the o ring im sure but I had a new one sitting in the garage so I changed it out.
What FPR do you have? Do you know how to adjust it?
Does the fuel filter has a designated in/out and if so, was it installed correctly?
The loss of pressure could be a problem with the pumps. It could be broken clamps or tears in the lines from the pumps to hat.

It's going back to the shop that just installed everything fuel related. They thinks something is wrong with the pumps.
If you're running a boost reference FPR, then pressure should be set around 39-40psi with the vacuum line disconnected. When it's reconnected, your gauge should read 39-40 psi minus half of whatever your car makes for vacuum at idle. So, for example, my car is set at 40psi with the vac line disconnected and makes 14inhg of vac at idle. So, 40-7=33. When I connect my vac line to the FPR, my gauge reads 33 at idle. Then adds 1psi of pressure for each pound of boost made.
If you're not running a boost reference regulator, then the gauge should read whatever you set the FPR to.

Yeah, im def not seeing that. Something happened shortly after I picked it up from the shop. We all think it is pump related.
